Simulating downtime in nagios

What's the best way to simulate (not schedule) downtime in nagios?
I want to "pretend" a service is down for a certain amount of time to
see what alerts nagios sends, etc.
I've come up w/ two bad ways to do this:
% Edit the config file to change the test to "check_dummy". I want to
run these "fire drills" via cron, and editing a file and restarting
nagios seems a little ugly.
% Submit a passive check saying the service is down, and reschedule
the next check 4 hours later, so the service is 'down' for 4
hours. This can be done using the nagios named pipe, so it's easy to
cron. Problem: doing things this way suppresses the alerts (when you
don't test a service, it doesn't send an alert).
Thoughts?
